EPQ Biology help please!Watch
It all depends on your particular biology course. When I did A-Level biology, adapting through evolution was definitely a topic, but not including the specific key words 'offensive or defensive'. If this is something your spec covers, you may have an issue. Even if it doesn't cover those words you may struggle to veer your essay away from being too similar to the course, as evolution is a massive topic across all biology boards. You may benefit from thinking about other ways you can cover evolution, that is sort of outside the box.
Hope this helps
